Based on a slew of good reviews, I recently bought a Jawbone II Bluetooth headset to use with my Blackberry. People I'm speaking with on the phone intermittently complain that my voice fades out and they can't hear me. At first, I thought that this was because I was sometimes turning my head during our conversations. But I'm receiving complaints from people that I speak with, even when my head isn't moving at all.

Have any one you experienced this problem and is there any solution to it?Thanks.Robert
